This document describes a suggested enhancement to HTTP, in which a user-agent and a server can use a single connection to exchange requests/responses for multiple requested hostnames for which the server is authorized to serve. This enhancement suggests that user- agents will prefer to re-use an existing connection if it can be used to other hosts, and presents methods for a server to announce hosts that are served by it, as well as a mechanism for the user-agent to validate that the server is indeed trusted to serve this hosts. This is highly relevant when the server is actually a surrogate (like in a case of a CDN server), or in multi-hosts hosting environments, where the same server serves multiple hostnames/domains and can improve performance by the reuse of established and already optimized connections.
